    Abstract: An international community of researchers is now flourishing in the area of cryptology-there was none half-a-dozen years ago. The intrinsic fascination of the field certainly is part of the explanation. Another factor may be that many sense the importance and potential consequences of this work, as we move into the information age. I believe that the various meetings devoted to cryptology over the past few years have contributed quite significantly to the formation of this community, by allowing those in the field to get to know each other and by providing for rapid exchange of ideas. CRYPTO 83 was once again truly the cryptologic event of the year. Many of the most active participants continue to attend each year, and attendance continues to grow at a healthy rate. The informal and collegial atmosphere and the beach side setting which contribute to the popularity of the event were again supported by flawless weather. The absence of parallel sessions seemed to provide a welcome opportunity to keep abreast of developments in the various areas of activity. Each session of the meeting organized by the program committee is repre­ sented by a section in the present volume. The papers were accepted by the program committee based on abstracts, and appear here without having been otherwise refereed. The last section contains papers presented at the informal rump session. A keyword index and an author index to the papers is provided at the end of the volume.

    Abstract: Although man's environment, from the interstellar dust to the earth beneath his feet, is composed to a large extent of finely divided material, his knowledge of the propert­ ies of such materials is surprisingly slight. For many years the scientist has accepted that matter may exist as solids, liquids or gases although the dividing line between the states may often be rather blurred; this classification has been upset by powders, which at rest are solids, when aerated may behave as liquids, and when suspended in gases take on some of the properties of gases. It is now widely recognized that powder technology is a field of study in its own right. The industrial applications of this new science are far reaching. The size of fine particles affects the properties of a powder in many important ways. For example, it determines the setting time of cement, the hiding power of pigments and the activity of chemical catalysts; the taste of food, the potency of drugs and the sintering shrink­ age of metallurgical powders are also strongly affected by the size of the particles of which the powder is made up. Particle size measurement is to powder technology as thermometry is to the study of heat and is in the same state of flux as thermometry was in its early days. Only in the case of a sphere can the size of a particle be completely described by one number.

    Abstract: The primary purpose of this handbook is to make available to general contractors, consulting engineers, construction managers, specialty contractors, and subcontractors, as well as to professors and students in Universities and technical institutes which offer courses on the subject, the fundamentals of construction management together with the most workable types of organization, and the necessary capabilities they must include to reasonably ensure success and minimize the possibility of failure in this most hazardous profession. The second and equally important purpose is to furnish equipment manufacturers, dealers, material suppliers, bankers, surety bondsmen, and others, who traditionally rely on financial statements and general reputation, something more concrete to look for-the type of management and organization, and its scope and capability-in deciding how far to go along with contractors with whom they deal or wish to deal. This, the second edition of the Handbook, is an updated version of the work published in 1973. The book covers very many subjects which are part of construction. The greatest care was exercised in consideration of their practical aspects based on the theory and practice of construction management and its structure, and the functions of the various departments, both in the field and central offices, that make up construction organization. Leading specialists in their particular fields were selected to write chapters on the vital segments making up the structure of construction management and organization. These fields include construction contracts and conditions, job organization by general types of projects, equipment maintenance and preventive maintenance and overhaul, engineering and estimating, scheduling and controls, data processing and the use of computer equipment in engineering and accounting techniques, office administration, corporate and cost accounting, payroll, employment and labor relations, safety, public relations, legal and contractural problems, banking and finance, taxes, surety bonding, insurance, pension and retirement problems and others.
